Good morning, Aziz

Octopuses have three hearts

Two branchial hearts pump blood through the gills, while a third, systemic heart pumps it to the rest of the body. Their blood is blue because it uses copper-based haemocyanin instead of iron-based haemoglobin to carry oxygen, which works better in cold, low-oxygen water. The systemic heart actually stops beating while an octopus swims, which is one reason they prefer crawling.

يَا أَيُّهَا الَّذِينَ آمَنُوا اسْتَعِينُوا بِالصَّبْرِ وَالصَّلَاةِ ۚ إِنَّ اللَّهَ مَعَ الصَّابِرِينَ

O you who have believed, seek help through patience and prayer. Indeed, Allah is with the patient.

Al-Baqarah 2:153
